IMPROVEMENT IN PROCESSES FOR CLEANSING GAS-RETORTS.

c Specification forming part of Lelters Patent No. 165,398

March 9, 1875.

To all whom it may concern:

Be it known that I, HORACE S. WOLF, of

I South Bend, in the county of St. Joseph and State of Indiana, haveinvented certain new and useful Improvements in Processes for CleansingGasdtetorts; and I do hereby declare that the following is a full,clear, and exact description thereof, which will enable others skilledin the art to which it pertains to make and use the same, referencebeing had to the accompanying drawings and to the let ters of referencemarked thereon, which form a part of this specification.

The nature of my invention relates to an improved process for cleansinggas-retorts; and consists in the application of Irish potatoes in theretorts, for making illuminatinggas, or in any other gas-eliminator.

The process is to place the potatoes, in their natural condition, in theretorts whenever they have become overcharged with the deposit orincrustation of the carbon, and require cleansing. The quantity ofpotatoes required will depend upon the amount of incrustation, from agallon to a half-bushel, which may be used without the coal, or with thefull charge of coal, as the case may require. When the podated July 6,1875; application filed tatoes are used alone a light draft is givengiven to the retort; but when the coal is used with the potatoes theretort is closed up in the ordinary manner of making gas. The resultfrom the use of this material is to destroy or neutralize the deposit orincrustation from the coal, while at the same time the quality of thegas "is improved. The retort is protected from the injurious effects ofthe overheating which is necessary to remove this deposit in theordinary manner, and no time is lost in the use of the retorts, as theyare regularly cleansed while the making of gas is continued.

Having thus described "my invention, what I claim, and desire tosecureby Letters Patent, is p The within-described process of cleansinggas-retorts by the use of potatoes, substantially in the manner and forthe purpose set forth.

In testimony that I claim the foregoing as my own invention, I affix mysignature in presence of two witnesses.
